I have a Next.js server. It’s up and running, and I know because when I do
wget myserveripaddress:30002 from the server itself, I get a (valid) index.html file.

It turns out there is a firewall installed by default. I was able to open it up (thanks to a little help from Digital Ocean support) with the command:
You can check the address is resolving, e.g the domain name is reachable. There might be a DNS conflict or some DNS cache that can prevent you to load the resource from your local machine.
You’ve correctly checked that the next.js server is running and also that the wget command will return successful result, but this happens only on the server. You can test this from another machine as well or using different network.
Are you using a domain? If it is, see if your domain is pinging from your Droplet:
Additionally, enter your Droplet via SSH and see in your logs if anything is being blocked.
